Key Takeaways from Saul Griffith

  • Firstly, Carbon Capture and Storage won’t arrive in time to save us
  • Secondly, we need a Wartime effort akin to World War II to retool and retrain the existing industry.
  • We need an abundance, not a scarcity mindset for renewables.
  • However, You can’t just keep improving efficiency all the way to Net Zero emissions
  • Every Fossil Fuel burning machine that breaks must be replaced with an electric counterpart, not repaired
  • “Jobs, Jobs, Jobs” – the energy revolution will be done primarily by tradespeople

  • Firstly, making decarbonising technologies the easy financial choice for everyday people is paramount
  • Secondly, many people live without savings, and use high interest credit cards for purchases
  • As a result, people will choose a cheater gas heater over a heat pump every time. Even when it will cost more in the long term, people choose cheap now.
  • Most Importantly, Training the future workforce needs to happen NOW in order to curb global warming to 2 Degrees C.


In conclusion, Saul Griffith and Danny Kennedy are attacking climate change from different angles. Both agree that we need massive action to transition the world off fossil fuels.
